DVD player. A DVD player is a device that plays discs produced under both the DVD-Video and DVD-Audio technical standards, two different and incompatible standards. Some manufacturers originally announced that DVD players would be available as early as the middle of 1996. These predictions were woefully optimistic.
The computer sits between the input and output devices. A computer program processes and digitises the input information. The result is then sent to an output device such as a screen. You click 'play' on your remote control, an input device. It digitises the input and sends this digital information to the DVD player. The computer inside the DVD player processes this input information and works out what to do. It will start to read the DVD. The video and audio information from the DVD is then sent to the TV screen and the speakers, the output devices.
